To all whom it may concern:

be it Known that we. ALBERT l. li LAMAN andJosnrnri. Cronin, citizens ofthe United States, residing at Luke, in the county of Qiliegan and Stateof Maryland, have invented certain new and useful Improvements inAutomatic Stock-Regulators for Paper- Making Machines; and we do declarethe following to be a full, clear, and exact descriptior; of heinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This nivention relates to an automatic stock regulator for paper makingmachines.

The object of the invention is to produce a simple and efficientapparatus for automatically regulating the stock to be fed to a papermaking machine to secure uniformity in the thickness and weight of thepaper.

in the accompanying drawings, Figure 1 is a front elevation partly insection of a 7 stock chest equipped with this improved regulator, partlyin section. Fig. 2 is a longitudinal section thereof. Fig. 3 is adetail. Fi 1- is a top plan of one of the weights.

in the embodiment illustrated a main box or stock chest 1 is shown,havin a compartment 2 arranged therein in Whic a balanced hopper orfunnel member to be described appears.

in one wall of the compartment 2 is an opening 3, provided with aclosure, referably in the term of a vertically slidab e gate carried byone end of a rod or post 5 and mounted in guides, as 6, disposed atopposite sides of the opening 3. A rack bar 7 18 adjustably mounted onsaid rod 5, preferably by means of spaced collars, as 8, which encirclesaid rod 5, and one of which is provided with a set screw 9, foradjustably securing the rack 7 to the rod 5.

Two standards 10 and 11 are fixed to the top of the chest 1 with anarched bar 10, connecting them, and through which the rod 5 passes, andis guided thereby, and a shaft 1 is journaled to turn said standards.

A toothed segment 13 is mounted between the free ends or anapproximately l-shaped member 1 1, through which the shaft 12 passes andto which the segment is fixed by set screws, as 14, passing through thearms of said member 1 1 and enga ing said shaft. The so ment 13 ispositione to mesh with the rec r bar 7.

A flexible element 15 is connected at one end with said V-shaped member14 and passes over a pulley 16, mounted on a suitable support, and isprovided at its other end with a weighted member 17 for a purpose to ibe described. i A hopper or funnel-shaped member 18 is disposed in saidcompartment 2, and is prefl erably provided with a bail handle 19. Thisi member 15 is suspended from the shaft 12 by means of a chain or othersuitable element 20, connected at one end to said bail 19, and at itsother end to a member 21 fixed to and extending laterally from saidshaft 12. This member 21 is preferably made ll-shaped with collars as22, formed on the free ends thereof, and which encircle the shaft 12,and are fastened thereto by means of set screws as 23.

A spout 24 is arranged opposite the gate 4 and opens into the funnel 18,to convey the stock which flows through said gate into the funnel.

The funnel or feeding hopper 18 is provided at its lower reduced endwith an opening 25, having an adjustable closure in the form of a gate26, carried by the lower end of a rod 27, which passes through an arm28, extending laterally over the side of the funnel near its top. Thisrod 27 is screw threaded at its upper end and is provided with a nut 29a apted to be adjusted on said rod to raise or lower the gate 26 to varythe size of the opening 25, to limit the amount of stock which passestherethrough.

An outlet pipe 30 leads fromthe compartment 2 and conveys the stocktherefrom to the machine.

The main box or chest is provided with an inlet 31 for the stock forcedinto the box from a pump, (not shown), and 32 is an outlet for theoverflow or stock not'needed in the machine.

proper distance to permit the required amount of stock to passtherethrough to the funnel, and from wh1ch it passes through the gate 26into the compartment 2, and out In the operation of this automaticreguthrough the pipe 30 to the machine. The

size of the opening 25 in the funnel is adjustr able by hand byoperating the nut 29 on the gate rod 27.

Should the funnel be filled beyond the dedownward an thereby lower thegate 4, and

rises and the wei ht falls, thereby moving the rack bar upwarc? andopening the gate 4, to permit more stock to flow therethrough into thefunnel. The stock from a pump (not shown), is admitted through the inlet31, and when it reaches a predetermined limit it flows out through theoverflow 32.

The weight carrying member is preferably constructed as shown in Fig. 2,being comy from said chest and connected to operate posed of a rod 17having a hook at one end or, engagement with the member 15 and a stop 17"at its other end. Weights as 17 of ordinary construction and varioussizes are adapted to be removably carried by the rod 17 to provide forthe counter-balancing of the hopper when filled to dilferent heights.These removable weights are preferably made in the form shown in Fig. 4.

An auxiliary weight 33 is preferably mounted on the shaft 12. Thisweight 33 is slidably and adjustably mounted on an arm 34 fixed to theshaft 12 referably by means of a set screw 35 whic 1 passes through asleeve 36 carried by the weight 33.

e claim as our invention 1. An automatic stock regulator comprising astock receiving tank or chest having an opening provided with anadjustable closure, a vertically movable feed hopper arranged to receivethe stock flowing from said chest and connected to open or close saidclosure on the rise and fall of the hoppier, said hopper having anadjustable stoc outlet, and counter-balancing means connected with saidhopper.

2. An automatic stock regulator comprising a stock receiving chesthaving an opening provided with an adjustable closure, a rod connectedwith sald, closure, a rack thereon, a toothed segment mounted to meshwith said rack. a weight carried by said segment, and a feed hopperarranged to receive stock from said chest and connected to operate saidsegment to raise and lower said rack bar and the closure connectedtherewith to 3. An automatic stock regulator comprising a stockreceiving chest having an opening provided with an adjustable closure, arod connected with said closure, a rack thereon,

a toothed segment mounted to mesh with said rack, a weight carried bysaid segment, and a feed hopper arranged to receive stock said segmentto raise and lower said rack bar and the closure connected therewith toregulate the supply of stock fed to the hopper,

and an adjustable opening in said hopper for permitting the stock topass therethrough to t 1e machine.

4. An automatic stock regulator comprising a stock receiving chesthaving an opening provided with an adjustable closure, a rod connectedwith said closure and having a rack bar adjustable thereon, ahorizontally disposed shaft journaled to turn on said chest, a toothedsegment fixed to said shaft in position to mesh with said rack, a wei htconnected with said se ment, a mem er fixed to and extending aterallyfrom said shaft opposite said segment, a feed hopper arranged to receivestock from the delivery opening of said chest and connected with saidlaterally extending member, and an adjustable delivery opening in saidhopper.

In testimony whereof we have hereunto set our hands in presence of twosubscribing wit nesses.
